Nyob rau hauv ntau cov kab mob hauv cov ntshav muaj tshuaj lom, cov ntsiab lus loj, cov kab mob ntawm cov kab mob thiab lwm cov kab mob pathological. Tshem tawm lawv, plasmapheresis yog siv - qhov zoo thiab kev xav ntawm kev siv hom no tas li sib tham hauv kev kho mob hauv zej zog. Qee cov kws tshawb fawb hais txog qhov tsis muaj txiaj ntsig ntawm qhov kev siv tshuab no, thaum lwm tus kws kho mob muab lus sib cav rau hauv nws txoj kev ua zoo.
Cov txheej txheem tseem ceeb ntawm txoj kev ua plasmapheresis yog pom (membrane) thiab gravitational (phau ntawv, centrifugation).
Pros thiab cons ntawm membrane plasmapheresis
Cov txheej txheem ntawm kev ua cov txheej txheem yuav pom zoo tas li ntshav ntawm cov cuab yeej tshwj xeeb - cov xim lim ntshav. Los ntawm cov catheter, ntsia 1 lossis 2 leeg ntawm tus neeg mob, ntshav tau noj. Nws khiav los ntawm cov ntxaij lim dej uas ntim cov tshuaj toxins thiab lwm cov kab mob pathological. Ntshav ntshav loj yog tov nrog cov isotonic kua thiab tam sim ntawd rov qab los rau hauv cov ntshav. Cov kua uas tau muab tso tawm rau hauv cov hnab yas cais tawm thiab tshem tawm.
Qhov zoo ntawm cov membrane plasmapheresis:
- kev ruaj ntseg;
- txij nkawm ntawm lub cev ua haujlwm ntawm lub plawv thaum lub sij hawm tag nrho kev sib kho;
- ceev (cov txheej txheem kav ib teev);
- tsis muaj kev hnov qab tsis kaj siab;
- Siv cov isotonic solution (biocompatible) thiab muaj cov tib neeg cov ntshav.
Tsis muaj qhov teeb meem loj hauv kev ua kom tau plasmapheresis. Hauv qee zaum, tus neeg mob yuav ua rau koj kiv taub hau, me ntsis loog ntawm qhov nqua , tsis muaj zog los yog xeev siab. Cov tsos mob tshwm sim sai sai rau lawv tus kheej.
Pros thiab cons ntawm phau ntawv qhia plasmapheresis thiab centrifugation
Cov txheej txheem gravitational ntawm tus txheej txheem no yuav tau khaws cov ntshav ntawm cov ntshav, uas yog lim dej los ntawm cov kua dej uas muaj anticoagulants (phau ntawv plasmapheresis) lossis centrifugation hauv lub tub yees.
Qhov tsuas zoo ntawm no technology yog cov nyhuv uas zoo sib xws rau daim ntawv membrane. Thiab cov disadvantages ntawm plasmapheresis gravitational yog ntau dua:
- cov txheej txheem siv sij hawm ntev;
- nws yuav tsis yooj yim sua kom huv sai ntim ntawm cov ntshav dej;
- tom qab ntshav kuaj nws yog tsim nyog los qhia cov khoom xyaw cov ntshav hloov los yog cov tshuaj pub dawb;
- yuav tsum muaj ntau zaug.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov zoo tshaj plaws thiab cov kev xav ntawm cov kev hloov ntawm plasmapheresis yuav tsum xub nrog cov kws kho mob tham. Qhov no yog ib txoj kev kho mob loj heev uas ua rau muaj kev qhia meej, thiab tsis yog ib txoj kev ntxuav ntawm cov ntshav .
